Abstract Porcine cysticercosis is emerging as a serious agricultural and public health problem in African countries. A study on the prevalence and morphometric of porcine cysticercosis was conducted at post mortem using palpation and incision technique of routine meat inspection. Out of the 247 slaughter pigs examined at post mortem, 8(3.2%) were infected and of this number 5(2.7%) were males and 3(5.1%) were females. Infection was more common in the Hampshire breed 7(3.5%), than the black Ashanti 1(3.3%). The Landrace breed had no infection. A total of 760 cysts were removed from infected animals. Out of this number, 261(34.3%) were removed from the shoulder muscle, 189 (24.9%) from the masseters, 176 (23.2%) from the tongue and 134 (17.3%) were removed from the heart respectively. 5 (0.65%) of the cyst were matured and 755 (99.34%) were immature. A total of 632 (83.2%) were viable while 128 (16.8%) were non-viable. Cyst morphometry indicated an overall mean ± SD (range) of 8.8±1.0(5-12) by 5.4±1.1(3-7) mm. Cysts from the shoulder had a mean ± SD (range) (length x breadth in mm) of 7.6±8.7(5-11) by 4.4±8.8(3-6) while those from the masseters were 7.8±6.9(6-12) by 4.7 ± 3.8 (4-6), tongue 8.7 ± 2.9 (6-12) by 5.7±2.6(4-6), and heart 8.6±3.5(5-12) by 5.3±3.7(3-7). The mean ±SD (range) number of hooks counted was 4.4±0.4 (4-6). This study has confirmed the presence of Cysticercus cellulosae and its morphological characteristics, which are useful aids in providing diagnostic and public health alerts.

The domestic pig (Sus scrofa domesticus) acts as the normal intermediate host of Taenia solium while man the definitive host (Cox 2002; Wadia & Singh, 2002). Pigs harbor Cysticercus cellulosae, the larval stage of T. solium. Pigs acquire the infection when they ingest Taenia solium eggs through the contamination of their food or water with human excreta. Man acquires infection by consuming raw or undercooked pork, which is among the most popular meat consumed in the world accounting for 44% of the world meat protein consumption (Githigia et al., 2006). Nigeria has a total of about 3.5 x106 pigs (Bourn et al., 1994) and this represents 4% of the total domestic livestock. Pigs have a unique ability to adapt and survive in areas where they are found, and are a potential protein deficit gap-filler, investment alternative and source of additional income among the human populace especially women (Ajala et al., 2006; Ajala et al., 2007). Cysticercosis is however a limiting factor of porcine husbandary in areas where this animals are raised especially in many developing countries of Latin America, Africa and Asia (Sarti et al., 1992; Geerts et al., 2002; Ikeh & Iweka, 2009). It is also estimated that over 10 million people are exposed to this larval worm which frequently cause neurocysticercosis and epileptic seizures among those affected (White Jr., 2000). There is inadequate information on porcine cysticercosis in the study area where pig husbandry is of free range with poor environmental and personal sanitation. This study was conducted to determine the prevalence and morphological characteristics of Cysticercus cellulosae. Materials and methods This study was conducted at the pig abattoir in Michika township, Adamawa State, Nigeria. A total of 247 pigs were inspected randomly at post mortem using palpation and incision techniques Sokoto Journal of Veterinary Sciences, Volume 10 (Number 1). June, 2012 SHORT COMMUNICATION Page 29 of 42 (SJVS, Vol. 10 no 1) during routine meat inspection. The tongue, masseters, heart and diaphragm were palpated and incised and visually inspected for presence of cysts. Cysts were classified as viable based on fluid transparency and visible scolex), dead (bluish green caseous masses) or necrotic (dark patches) as described by Thornton & Gracey (1976). Prevalence of cysts was recorded as percentage based on sex, age and breed of pigs, while the length and breadth of each cyst in millimeters recorded as mean ± standard deviation (SD).
